Author an ordered lists of formulas sub-type
This sub-type is authored by selecting the Ordered lists of formulas option from the Sub-type drop-down list during mathematical formula question authoring.
Examples of accepted syntax for defining the Answer field value for this sub-type are:
- 2, 4, 8, 16
- sqrt(3)/2, 1/2, sqrt(3)
The ordered lists of formulas sub-type Answer field:
- Accepts a list of numbers or formulas separated by commas (,)that are in a specific order.
- Requires student responses to be entered in the same order as defined by the correct answer.
- Accepts equivalent responses.
- Doesn't accept a list enclosed in parentheses.
TIP: Be sure to author instructions for your students to inform them to enter an list of formulas in a specified order that's separated by commas.
NOTE: The ordered lists of formulas question is one of the ten sub-types of the mathematical formula question. Check out Choose a mathematical formula question sub-type for an explanation of each of the ten available mathematical formula question sub-types.
TIP: Check out Author a mathematical formula question for full question authoring instructions.
Example of this sub-type
- Question statement:
Compute the exact values of:
sin(π/3), cos(π/3), tan(π/3)
Provide your answer as an ordered list based on the question order. Separate your list with commas.
- Answer field syntax:
sqrt(3)/2, 1/2, sqrt(3)
Example of this sub-type with an algorithm
- Question statement:
Compute the exact values of:
sin($nπ/$d), cos($nπ/$d), tan($nπ/$d)
Provide your answer as an ordered list based on the question order. Separate your list with commas.
- Algorithm:
$i=rint(7);
$n=switch($i,"","",2,5,5,7,5);
$d=switch($i,3,4,3,4,3,4,6);
$sinans=switch($i,"sqrt(3)","sqrt(2)/2","sqrt(3)/2","-sqrt(2)/2","-sqrt(3)/2","-sqrt(2)/2","1/2");
$cosans=switch($i,"1/2","sqrt(2)/2","-1/2","-sqrt(2)/2","sqrt(2)/2","1/2","-sqrt(3)/2");
$tanans=switch($i,"sqrt(3)",1,"-sqrt(3)",1,"-sqrt(3)",-1,"-sqrt(3)/3");
- Answer field syntax:
$sinans, $cosans, $tanans
NOTE: The dollar sign ($) character can only be used in mathematical formula questions when it's a part of a variable name. Be sure to define algorithmic variables in the Algorithm pane in order to use them in the Answer field.
